allowing foreign letters?

[codrgii]

Would someone tell me how to allow foreign letters, normal english letters and numbers using the preg_replace php function?

I forgot to add, these foreign letters are like í and so on.

Add '\pL' or '\p{L}' to match unicode letters. You also have to set the 'u' (for utf- pattern modifier.

/[\p{L}a-z0-9]/iu

I tried your example but when i do, nothing shows, not even the basic a-z or numbers.

It wasn't meant to be plug and play... I don't know what you're trying to replace or allow, I was just showing you an example. Maybe if you post the code and what you're trying to do...

It says it all there.  I want to only allow the basic English letters and words a-z0-9 but with that also allow foreign accent letters, then remove anything else.

So you want to remove anything that's NOT one of these characters? Use ^

$string = preg_replace("/[^\p{L}a-z0-9]/iu", "", $string);

Remember that space is included...
